Android Question [Solved] Widget NullPointerException at ConfigureHomeWidget(...)

[fredo]

While working with Erel's tutorial I and II I might haved missed it but it is important to respect the special case how views are handled in Widgets.

At some point experimenting I came across this error:

~e:starter_service_create (java line: 165)
~e:java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String java.lang.String.toLowerCase(java.util.Locale)' on a null object reference

~e:    at anywheresoftware.b4a.BA.raiseEvent2(BA.java:186)
~e:    at anywheresoftware.b4a.BA.raiseEvent(BA.java:166)

It took me a while to crawl to the cause and found it here:

So in this case it was using the text property at design time which should stay empty.

I thought it might help someone who searches the forum for a hint.
